MACHINERY FOR DRESSING COIVIBS.v

Specification of Letters Patent No. 4,321, dated December 20, 1845.

l To all whom t may concern .i

Be it known that I, CALVIN B. ROGERS, ot Saybrook,l in the county of Middlesex and vState of Connecticut, have invented a new and useful Machine for the Purpose of Scraping, Smoothing, and Shaping Ivory Comb-Plates and other Articles of a Like Character; and I do hereby declare that the following is a full and exact description of the same. v

In the accompanying drawing, Figure l is a perspective view of such of the operating parts of the machine as are on the top sides and ends of the machine, A A being the basis or support thereof. Fig. 2 is a perspective view of the box or case B with its door open. Fig. 8 is a perspective view of the under side of the wheel C and top of the upright shaft D. Fig. 4 is a perspective view of the last end of the large bed E E with the top bed G taken off. Fig. 5 is a perspective view of the under side of the top bed G with its spring Vand piece detached from the large bed E E. Fig. 6 is a perspective view of the inside of the box or case F which receives the plates after passing through the beds. Fig. 7 is a perspective view of the large bed E E and the top bed G, showing their relative position to each other when in operation, and showing also the position of the vplates of the springs and pieces, and of the cylinders or rolls, t-he whole being detached from the other parts of the machine. Fig. 8 is a perspective view of the top part of the levers J, Ja showing the position of the chisels and the manner by which they are secured to said levers.

Fig. 1 H H are two fra-mes resting upon the vbasis of the machine. I, I, two cross pieces one on each frame supporting the ends of the large bed E E, these cross pieces are attached to the frames H H by screw bolts through the slots b b and can be raised and depressed at pleasure. E E the large bed extending from one frame to the other the ends rest-ing upon two screws through the cross pieces, I, I and attached by screws on each side, by which the position of the bed E E may be changed as may be necessary. On the first part of this bed E E are four posts, two on each side as seen at a a projecting above the bed, and acircular projection on the lower side with a corresponding circular cavity on the upper side giving room for the cylinders or rolls, a representation of which may be more distinctly seen,

and also of the upper cylinder, u, and the position of the` lower one in Fig. 7, the two cylinders being of equal size. Between the posts a a as seen in Fig. 7 at n i are placed the boxes or bearings governing the cyliny ders. The plates on coming from the -box B are received between the two cylinders as seen at m z' Fig. 7, and by them forced through the beds into the receiving box F. The pressure of the plates between the cylinders is regulated by the screws in the tops of the posts and the springs c fv, the springs bearing upon the boxes of the upper cylinder. The inner part of this large bed E E is made to admit smaller beds in which the F z' is removed and another supplies its place fitting the scraped side of the plate. The top bed G is attached to the large bed E E by eight screws, 4 of which go through the top bed Gr and screw into the large bed E E, the other four screw through the top bed G the ends resting upon the top of the large bed as seen in Fig. 7 at s, s, s, s, by these screws the top bed G is changed as may be desired.

Near the center of the top bed G directly under the chisels of the long lever J a is a space through the bed as seenat' Z Fig. 1, or more distinctly seen at A B Fig. 7, sutlicient for the chisels to play back and forth over the plate. The plates in passing through this bed Gr are pressed up by a spring and piece on the under side as seen space A B as seen in Fig. 7 'under the chisels. Thus plates varying in-thickness, sustain the same position on the upper side to the chisels, thereby allowing the chisels to take no more from a thick plate than from a thin one, not reducing the thickness of one more than another.

J and J a two levers or frames to which the chisels e e e e that scrape smooth and shape the plates are attached. J the short lever with its chisels e e takes off the plate at and near the edges leaving them the precise thickness required; J a the long lever with its chisels c e scrapes and smooths the center portion of the plates. By the arrangement of the t-op bed Gr above described plates varying in thickness are equally scraped by the chisels of the long lever J a. These levers J and J a are hung upon the shafts it t turning in boxes z' i, z" i near the lower end of said levers. These levers are propelled by the wheels or cranks Z Z connected to t-he levers at 7c k by the rods j j. m m are two springs bearing upon the levers to counteract in a measure the tremor caused by their motion. In the upper part of these levers is a space as seen at K K in Fig. 1 or at K 'a' Fig. 7 suiicient for the large bed to pass through and also giving room for their action; L L two cross pieces one upon each lever holding the chisels e e e e and secured to the levers by screw bolts passing through the slits in the levers as seen at n n n n and moved up or ydown by upright screws 0 o o 0 on the top and sides of each lever. The chisels e e are secured to the cross piece as seen at p p or more distinctly in Fig. 4 at P by a screw and piece, the piece being so adapted by its shape and also the center of the cross piece that by the use of one screw both chisels are firmly held to their places.

By the arrangement of the levers J -and JEL the desired shape is given to the plates, the two circles being graduated by the length ofthe levers. Circular slides may be used to hold the chisels in the place of the levers, but for the present Iprefer to use the levers. M a bar on each side connecting and strengthening the frames. H H, g guides keeping the long lever in its proper place. O O a frame attached to A A the basis of the machine supporting the box B the shaft D and their fixtures. 'w rw springs and pieces more distinctly seen in Fig. 7 at fw i w i attached to the large bed E E keeping the plates down to the small bed F 'L'. a: w side springs seen more distinctly in Fig. 7 attached to the large bed keeping the plates against one side of the small beds.

The plates to be scraped are placed in the box B on the front part of the machine which box may be seen showing the position of the plates in Fig. 2. The plates are made to pass out singly at the bottom of the box B into the bed E E to the cylinders before described, by means of a at piece of steel or other substance thinner and narrower than the plates attached to the slide N and moved v back and forth through the bottom and spaces of the box- B by the wheel C connected by the rod s to the slide N, at each forward motion of this slide N, and the piece attached to it a plate is taken from the box B and pressed into the bed between the cylinders, the space next to the bed E E being only sufficient for one plate to pass out at a time, and the space at the other end as seen at R z' Fig. 2 being only sufficient for the piece attached to the slide N to play through.

The wheel C is connected to the shaft D as seen in Fig. 3 by two pieces A A and a set screw s forming a grip on the under side of said wheel. These pieces A A are fitted to a groove in the' outer edge of the small wheel C z' on the upper end of the shaft D. By this arrangement of the wheel C any power required may be given to the slide N, it also adapts the motion of the slide N to the motion of the cylinders in carrying in a plate into the machine the small wheel c z' turning in the grips A A. By this arrangement also plates of unequal length are equally forced between the cylinders, and

when a plate is stopped by any obstruction4 in the beds the small wheel c i then turns in the friction grips A A of the wheel C, doing no injury to the machine or plates. A i Fig. l the main shaft to which the propelling power is applied. H i and S t' smaller shafts by which the proper motion is communicated to the cylinders and to the upright shaft D.

F the box to receive the plates from the top bed Gr, `the plates are pressed downward by a spring a on the under side of the lid as seen in Fig. 6, the plates resting upon a small bed to which is attached a tapering rod X z' passing through the bottom of the box and clasped by springs 1 r attached to said box. When a plate enters this box the bed and rod X i is pressed down by the spring a to receive the plate and so on unt-il the box is filled. By the tapering rod X z', and springs 1' 1", the weight of the plates are equalized, thus requiring no more power in the spring for one plate than for many plates. In scraping the last side of the plates the receiving box F may be detached.

Having thus fully described the manner in which I construct my machine for scraping, smoothing, and. shaping ivory comb plates and other articles of a like character, what I claim therein as new and desire to secure by Letters Patent, isf` l. The manner in which I have arranged the apparatus for carrying the plates between the cylinders, consisting of the box B the slide N with its piece and the wheel C,

connected by the rod S to the slide N and to the shaft D by the small wheel c 7l and the grip A A theretofore described and seen in Figs. l and 3 operating substantially as before stated.

2. I claim the manner in which I have arranged the top bed G whereby plates varying in thickness are equally scraped, not reducing the thickness of one more than another; said arrangement consisting of the spring S and piece S z' as seen in Fig. 5 and the position of said bed with its space A B as seen in F ig. l.

3. I claim the manner in which I have arranged the chisels for scraping, smoothing, and shaping the plate, said arrangements consisting of the levers J and J a; the cross pieces L L and the apparatus for. securing the chisels to the crosspieces seen at P i, Fig. 8, and for securing the crosspieces to the levers as seen at n n fn, n Fig. 1 or at H H Fig. 8 and for the movement up or down for the same by the screws as seen at L z' L z' Fig. 8.

4. I claim the manner in which I have arranged the box4 F to receive the 'plates from the top bed G consisting of the spring z on the under side of the bed seen in Fig. 6 and the bed with its tapering rod z' clasped by the springs r r under the said box, operating as before stated.

And I hereby declare, that I do not intend by these claims to limit myself to the exact form, or arrangement of the respective parts and combinations as herein described and represented; but to vary these as I may deem expedient; while such arrangements and combinations are substantially the same with those herein fully made known.
